Activate Bottomless while Necrovalley is on field?

Necrovalley:All "Gravekeeper's" monsters gain 500 ATK and DEF. Cards in either player's Graveyard cannot be banished. Negate any card effect that would move a card in the Graveyard, other than itself, to a different place.

vs

Bottomless Trap Hole

When your opponent Summons a monster(s) with 1500 or more ATK: Destroy that monster(s) with 1500 or more ATK, and if you do, banish it instead of sending it to the Graveyard.

Who wins?

Bottomless Trap Hole wins because, it says "When your opponent Summons a monster(s) with 1500 or more ATK: Destroy that monster(s) with 1500 or more ATK, and if you do, banish it instead of sending it to the Graveyard," it removes from the field. NOT from the graveyard.

That is true. when i faced someone that was using gravekeepers and i bottom their descendant and he will send him to the grave. and i'm like no, he goes to banished. Then he'll go no!!!! Necrovalley prohibits him to go from the graveyard to Banished. And im like noob, and i post like 5 different yugioh links that showed that descendant would go to Removed From Play instead of send to the grave. Then what do you know? He says F U and rage quits completely off of DN XD
